Abstract
Abstract Study in three phases is an adaptive site-specific sound installation that includes 22 solenoids placed on metallic arches that surround visitors and react to environmental perturbations, creating a self-regulating soundscape of metallic hits that serves to renew the visitors’ acoustic perspective. Adaptivity is a crucial aspect of the work: Similar perturbations will not generally cause similar reactions from the installation based on past interactions, thus allowing evolution over time to play a key role artistically and technically. This article discusses the author's position on adaptivity in music interaction and composition and reports on the technical and artistic aspects of the installation.
Highlights
An adaptive system is one capable of modifying its internal variables as a function of its inputs in order to fulfill a task [1,2]
Adaptive systems are increasingly used in musical interaction because of their adaptability to environmental perturbations, creating a connection between audience and system
This connection is deeper compared with nonadaptive systems: In a generically interactive installation, the system directly reacts to the inputs; implicit feedback between output and input is relegated to a secondary, almost inconsequential, role
Summary
An adaptive system is one capable of modifying its internal variables (state) as a function of its inputs in order to fulfill a task [1,2]. Adaptive systems are increasingly used in musical interaction because of their adaptability to environmental perturbations (noise, turbulence), creating a connection between audience and system. This connection is deeper compared with nonadaptive systems: In a generically interactive installation, the system directly reacts to the inputs; implicit feedback between output and input is relegated to a secondary, almost inconsequential, role. Environment and system are structurally coupled [3], influencing each other in a circular way. An adaptive system is not completely predictable in response, and we wonder if it is building its own knowledge of the environment and how. Adaptive systems especially in the arts can subvert power relations between humans and systems, allowing new and unexplored interactions
